Abstract

The present invention relates to a method for efficiently controlling an MTC device attempting a delay tolerant access in a 3GPP system. The present invention provides a method for effectively providing a backoff time to prevent load on a wireless network, which can occur when many MTC devices in a single cell simultaneously attempt access.
